The most frequent fossil, however, is the little crustacean before named, Estheria minuta; this.str0ngly resemblesa small bivalve shell, and is covered with delicate markings. Every here and there calcareous nodules occur in the sandstone, which when broken up frequently yield this interesting fossil, which is not more than a quarter of an inch in diameter.

Black carbonaceous markings darken the surface of the sandstone beds here and there, probably the result of the decay of seaweeds. Curious spottings, due to a trace of manganese, also abound. The surface of many of the marly beds is covered with markings, usually described as worm-tracks.
